Mccb Function Is As The Medium Voltage Circuit Breakers.
Rating 160A Type Hha161p
In Choosing A Circuit Breaker Of Things That Should Be Considered Are:
The Characteristics Of The System In Which The Circuit Breaker Is Installed.
The Need For Continuity Of Service Of An Electrical Power Source.
The Rules And Standards In Force Protection.
Characteristics Of The System
1 . System Voltage
Operating Voltage Of The Circuit Breaker Must Be Greater Or Equal To The Minimum Voltage Of The System .
2 . The Frequency Of The System
Rated Frequency Of The Circuit Breaker Must Be In Accordance With The Frequency Of The System . Merlin Gerin Circuit Breakers Can Operate At A Frequency Of 50 Or 60 Hz .
3 . Rated Current
Rated Current Of The Circuit Breaker Must Be Adjusted To The Size Of The Load Current Which Is Passed By Cable , And Should Be Smaller Than The Threshold Current Is Allowed To Pass On The Cable .
4 . Breaking Capacity
Breaking Capacity Of The Circuit Breaker Shall Be At Least Equal To The Prospective Short Circuit Current Which May Occur At Any Point In The Installation Where The Circuit Breaker Is Installed .
5 . Number Of Poles Of Circuit Breaker
6 . The Number Of Poles Of The Circuit Breaker Is Dependent Upon The Grounding System Of The System .
Continuity Needs Resources
Depending On The Level Of Continuity Of Service Requirements Of Power Resources , The Selecting Circuit Breakers Must Be Considered :
1 . Discrimination Breakaer Total Of Two Circuit Placed In Series .
2 . Discrimination Is Limited ( In Part ) , Discrimination Is Only Guaranteed Up To A Certain Level Of Fault Currents .
